It is necessary to make check of density of electrolyte in the accumulator each 3 months to define load ability of the accumulator.

Check is made by the densitometer. When determining density of electrolyte it is necessary to consider accumulator temperature. At a temperature of electrolyte below 15 °C on everyone 10 ° less than this temperature subtract value 0.007 from the measured density. For everyone 10 ° over 15 ° add 0.007.

Electrolyte density in the accumulator has to be in the following limits:

Temperature

It is above 25 °C

It is below 25 °C

Full charge

1,210 – 1,230

1,270 – 1,290

Charging for 70%

1,170 – 1,190

1,230 – 1,250

Discharged

1,050 – 1,070

1,110 – 1,130

Measure density of electrolyte in each can. The difference in density 0,04 or more between two any banks indicates loss of electrolyte or sulphation of plates.

If electrolyte density between two any banks differs more, than on 0,04 accumulator is subject to replacement. If density of electrolyte is lower demanded, but identical in all banks, the accumulator needs to be charged.

In case of use the neobsluzhivaa of the my accumulator can check a condition of the accumulator only the voltmeter. In accumulators with the built-in indicator of degree of state of charge the condition of the accumulator is determined by color of the indicator. Green color of the indicator corresponds to a full charge of the accumulator. Black color of the indicator indicates the need of accumulator charging. Blue color of the indicator testifies to the low level of electrolyte in the accumulator.
